Lives in groups at the surface of small creeks with clear waters. Also found in ponds where it is found together with Rivulus (Ref. 27188). Feeds on Ephemeroptera larvae and ants. The spawned eggs are deposited on submerged leaves and are guarded by the males (Ref. 12225). During incubation, the male oxygenates the eggs (Ref. 27188).
